Why Public Blockchains Are Winning the Race Against Permissioned Systems in Finance
The Debate Over Blockchain in Traditional Finance
Traditional finance firms face a big choice. They can pick open public blockchains or stick with closed private systems. A recent discussion between ARK Invest and a16z crypto shows strong views on both sides.
ARK Invest research director Lorenzo Valente spoke out against the idea that banks and asset managers will only use permissioned blockchain tools. He pointed out that
Evidence From Real Growth in Tokenized Assets
Tokenized assets are growing fast on open networks like Ethereum. These assets include real estate, bonds, and funds turned into digital tokens. Public chains allow anyone to see and trade them with clear rules. This openness brings more users and better liquidity than closed systems.
Private blockchains often stay small because they limit who can join. They copy some blockchain ideas but miss the network effects that make public chains strong.
Crypto Native Companies Lead the Charge
ARK also noted that firms like Circle and Coinbase are in the best spot to build new financial tools. These companies already understand both crypto and rules. They can create systems that work for everyone while meeting legal needs.
Old banks may move slow. They have heavy rules and old systems. Crypto native players move faster and can add compliance later without losing the core benefits of decentralization.
What a16z Crypto Said About TradFi Plans
The other side argues that banks want blockchain features such as tokenization and fast settlement. But they want to keep full control. This means permissioned networks that fit their current compliance and governance needs.
They call it programmable financial infrastructure. It borrows good ideas from blockchain but stays inside the old system.
Another View From Sentora on Hybrid Adoption
Sentora co founder Jesus Rodriguez offered a middle path. He believes institutions will take the base technology from DeFi. Then they will add their own layers for custody, checks, and controls.
This approach could let them use the speed and transparency of public chains while still following rules. It shows that full rejection of DeFi ideas may not happen.
Why This Matters for the Future of Finance
The outcome will shape how money moves in the next decade. Public blockchains offer global access and lower costs. Permissioned systems offer safety for big players. The real winner may be a mix where both work together.
Investors and users should watch how tokenized assets grow on Ethereum and other open networks. Early signs point to public chains gaining ground fast.
